mysql update query with inner join

Question

I have two tables customer and order. I want to update different values in both tables with one query. For example customer table has a city column and value is germany and orde

Answer 1

It is very simple to update using a join query in SQL.You can even join two or more tables. Here is an example :

    UPDATE customer_table c 

     INNER JOIN  
          employee_table e
          ON c.city_id = e.city_id  
     INNER JOIN 
          anyother_ table a
          ON a.someID = e.someID

    SET c.active = "Yes"

    WHERE c.city = "New york";

Answer 2

MySQL supports this operation:

UPDATE customer c INNER JOIN
       order o
       ON c.cust_id = o.cust_id
    SET c.cust_city = 'Lahore',
        o.order_status = 'Resolved'
    WHERE c.cust_id = 2 ;

Note: order is a really bad name for a table, because it is a SQL keyword. Choose names for things that do not need to be escaped.
